My point exactly. Bits is bits, so if it isn't awesome, something is
wrong.

As it should be in any decently designed DAC - if your DAC is sensitive

It's not particularly quiet no, and the gain on the DAC through the
pre-amp is very high which makes this worse. Result is noise level is
relatively obvious if it steps up a few dB (such as stepp
if you think it's the SBT, i personally would have no qualms about a
factory reset on the spot. i have done that with several devices over
the years. i also like to go for a clean reinstall of LMS (it's why i
keep a virginal copy of the original virtual machine) whenever some
weird issue appears.

Pretty sure I have power cycled the amp during this phase before and it

I'm even trying to use small amounts of digital attenuatiin to my

practice you dont hear the squeezebox volume control imo at least not

It's a 24b/96k DAC. Have to admit I assumed the SB was sending 16 bits
because the source is a 16 bit flac.. Maybe that's not true.
I am however certain that using the digital volume or replaygain on the
SB results in poorer, not just quieter, sound...
Well if the dac is a true 16bit design i would not use digital volume,
the spdiff standard is a bit weird it is basically 16 bit + 8 extra bits
legacy design just discards the extra bits ( backwars compatible ) so
you would runcate at the dac interface if using digital
Volume you would never get 1

Disabling RG will not hurt quality, but you lose the RG functionality,
so there should be a somewhat better reason that "it won't hurt"

My view really is that disabling RG and setting fixed 100% vol will

Well I have a 16 bit DAC with an analogue pre-amp and volume control

So you have a 16-bit DAC that does the volume processing at 16 bits?
Must be a really old one. I
